[George MacKerron]

Thanks for raising an issue.

I have some projects where @neondatabase/serverless is working on Cloudflare Pages, so it would be helpful if you could provide a repo (or commands for setting up a project) that shows the problem.

[Jan Piotrowski]

This might be related: cloudflare/next-on-pages#499
Shows a problem that only happens when using @cloudflare/next-on-pages, and links to other issues on Cloudflare's side.

[George MacKerron]

It looks as if this may have been fixed by a recent change to Workers: cloudflare/workerd#1513 (comment)

@Gregoor Is your problem resolved?

[Gregor]

Sorry, I don't have the project anymore as we jumped ship somewhere else. Will post here again if I try it again

[George MacKerron]

Sorry to hear that. Thank you.
